Application flied larch 19, 1917. Serial No. 155,856.

To all whom it may concern:

Be it known that I, BENJAMIN D. Baaaow, a citizen of the United States, and resident of Detroit, \Vayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a, specification,

This invention relates to hydrocarbon motors and particularly to cylinder construction.

One of the objects of the invention is to produce a built up cylinder structure of a commercially practical form and one in which lightness is particularly noticeable.

Another object of the invention is to produce a plural cylinder structure in which several cylinder elements are connected by an attached jacket.

Another object of the invention is to form a plural cylinder structure in which adjacent cylinder elements are connected by an expansion piece welded to adjacent parts of the cylinder and by a jacket connected to both cylinder elements.

Another object of the invention is to form a cylinder structure in which the cylinder elements may be made of steel forgings and the jacket of sheet steel welded on to the cylinder elements.

Another object of the invention is to form a plural cylinder structure in which the cylinder elements are arranged close together and provided with a sheet metal jacket which does not pass between the cylinders but leaves a single water space between adjacent cylinder walls.

Another object of the invention is to provide a plurality of cylinder elements with a built up steel jacket of novel construction.

Other objects of the inventionwill appear from the following description taken in connection with the drawings which form a part of this specification and in which- Figure 1 is a side elevation of a cylinder structure built according to this invention;

Fig. 2 is a sectional view on the line 22 of Fig. 1 looking upwardly as shown by the arrows;

Fig. 3, is an enlarged vertical sectional view of a lower portion of two adjacent cylinders,

Fig. l is an enlarged perspective view of a connecting piece used between adjacent cylinders, and

Fig. .5 is a perspective view of the lower portion of a cylinder element as it appears e'fore the attachment of the jacket.

Referring to the drawings. 10, represents a cylinder structure built in accordance with this invention. Three cylinders are shown in this structure but it will be understood that any desired number of cylinders ma be grouped within reasonable limits.

e cylinder elements are indicated at 11 and each of them is formed with an attaching flange 12 at its lower extremity and projections 13 and 14 near its upper end, in which are the various cylinder ports and other openings. Each oi? the cylinder elements is also formed with a flange 15 a short distance above its lower end, this flange being preferably of L shape which provides a downwardly extending skirt 16 around the periphery of the flange. Both of the flanges 12 and 15 are cut away somewhat or flattened oif along one side of the cylinder so that two cylinders may set closer together without flange interference and in the case of three cylinders the center cylinder is cut away on two opposite sides. Thesecut awayflat parts are indicated at 17 and 18 respectively, on the drawings, being particularly shown in Fig. 5,

The tops of the cylinder elements are connected and covered by a cover piece 19 which may be welded or otherwise secured to the cylinder around the projections 13 and cylinder jacket 20 which surrounds the several adjacent cylinders. This jacket 20 is referably made. of sheet steel and it may e in a single piece or several pieces welded or otherwise joined together and as shown it surrounds the three cylinders and is connected to the flanges 15 of each of the cylinders by welding its lower edge to the skirts 16 of said flanges.

When two adjacent cylinders are arranged in the close proximity shown in the drawings it is desirable to have but a single jacket of water between them and the present construction contemplates this arrangement. The jacket 20 follows the cylinder wall part way between the adjacent cylinders and then curves at about right angles to form the jacket of the next cylinder.

This leaves an open space at the bottom of the jackets between the cylinders, which space is filled by a piece 21 which is secured as by welding to the adjacent flat parts 18 of the flanges 15. This piece 21 is shown as of inverted U form and its ends are welded to adjacent parts of the jacket 20 thereby completing the inclosure of the cylinders to permit ofcooling them by circulating water through the chambers or inclosed spaces formed by the jackets.

It will be understood that in building up this cylinder structure the pieces 21 are first secured to the respective adjacent cylinders and the jacket 20 is then welded into position around the cylinders and to the flanges 15 and the pieces 21. By this construction more or less flexibility of the structure is' attained and not only may the cylinder elements be properl positioned in exact relation to each ot er upon the crank case or other support to which they may be bolted, but any other slight expansion or contraction between the cylinder elements may take place without in any way injuring or jeopardizing the construction of the jacket parts.

While but one form of the invention is shown and described it will be understood that other forms may be made without departing from the invention as set forth in the claims.

Having thus 'described my invention, what I c aim and desire to secure by Letters Patent is:

1. A motor. cylinder structure comprising a plurality of cylinders each having an attaching flange at the lower end and a pcripheral flange above said attaching flange, one piece expansion pieces secured between the adjawnt peri heral flanges, and a jacket surrounding said cylinders and secured to said expansion pieces and to said peripheral flanges.

2. A motor cylinder-structure comprising a plurality of individual cylinders, and one piece expansion strips of substantially inverted U shape welded therehetween adjacent to the lower ends.

3. A motor cylinder structure comprising a plurality of cylinders each having a pcripheral flange adjacent to the lower end thereof, each flange being flattened on the side next another cylinder to form adjacent parallel faced flanges, said flanges having downwardly turned skirts forming welding faces, and a jacket surrounding said cylinders and welded to said flanges.

4. A motor cylinder structure comprising a plurality of cylinders each having a pcripheral flange adjacent to the lower end thereof, each flange being flattened on the side next another cylinder to permit close arrangement of cylinders, said flanges havin downwardly turned skirts forming we ding faces, one piece expansion ieces of substantially inverted U shape wel ed to the flattened parts of said flanges, and an outer jacket surrounding said cylinders and welded at the lower edge thereof to the circular portion of said flanges and to the ends of said expansion pieces.

5. A motor cylinder structure comprising a plurality of c linders, a top plate covering the tops of sai cylinders, a side jacket surrounding said cylinders, and expansion strips joinin said cylinders together, said top plate, si e jacket and expansion str1 s being joined so as to completely incase t e cylinders.

6. A hydrocarbon motor comprising a. plurality of cylinders each having a peripheral flange, a top plate covering the tops of said cylinders, a side jacket surrounding said cylinders, and expansion strips welded to said flanges and joining said cylinders together, said top plate, side jacket and expansion strips being joined so as to completely incase the cylinders.

In testimony whereof I aflix my signature.
